36 gallon bow front build invert addition help please

[Cchamby]

I have a 36 gallon bow front and have finished my build. I just upgraded my pump and filter to the Aqueon 75 (400 gph) and currently have the following fish: 2 ocellaris clownfish, 2 Kaudern cardinals, 1 yellow tail blue damsel, 1 purple pseudochromis, 1 pink spotted goby, and 1 lemonpeel angel. I also have the following inverts: 5 Mexican turbo snails, 3 emerald crabs, 2 serpent sea stars, 1 blue legged dwarf hermit crab and 1 peppermint shrimp. Can anyone recommend what inverts I should add next if any?

Anemone crabs are awesome.

I'll have to check them out and see if I can find some. Thanks
